DCMI on the Seeed Arch Max
Does anybody know if DCMI works on the Ach Max? I have been trying to get it working, it mostly hangs when the DCMI interrupt is enabled. I have used STMCube to generate the driver. Unless someone can come up with a definitive answer, I will re-write using the STM Lib and not mbed, to see if the mbed lib is causing problems.
Be the first to answer this question.
Did you define the interrupt handler correctly? I don't think the mbed lib itself can cause the issue, but while not 100% sure, I believe the mbed STM drivers included were slightly modified to make them not use anymore the System Tick timer (which was a bad decision in the first place to use). That could be related to it, but I am not sure at all if this is actually the case!
